%X Ray-space representation is an effective approach to realizing real-time free viewpoint video system with complicated scenes. A feature point based ray-space interpolation method is proposed for arbitrary viewpoint image rendering in this paper. At first, feature points of ray-space slice or image are extracted, then, considering occluded problem, the feature points are matched based on correlation-based criterion, and each ray-space slice is segmented into different regions. Finally, an interpolation operation is applied to the segmented regions. Experimental results show that the proposed method can interpolate ray-space data fast and render arbitrary viewpoint images, and PSNR of the interpolated ray-space data is high, as well as quality of the rendered arbitrary viewpoint images.
